Unit 6: 2D Geometry and Patterning
Learning Goal: we will have a strong understanding of 2D geometric figures, symmetry, and patterns.
Success Criteria: we know we are successful when we are able to...
Success Criteria: we know we are successful when we are able to...
 describe, sort, and compare 2D figure according to the numbers of side and numbers of vertices
 recognize figures that have symmetry, or matching parts.
 make patterns using materials and pictures of 2D figures.
 Use positional language to describe movement and location: slide to the left, turn, above, beside.
Comparing 2D Figures: Sides and Vertices
To compare our different figures/shapes, we will look at two attributes to determine the difference between the shapes. These two attributes are sides and vertices. In our class, we define a side as any line which connect two vertices. A vertex (plural is vertices) is a point where two lines meet.

Symmetry
Geometric Figure Movement  Flip, Slide, Turn
Flip: to turn a shape over creating a mirror image. This is when you would see examples of symmetry.

Slide: to move a shape without rotating or flipping it. The shape looks exactly the same, just in a different place.

Turn: A circular movement. Rotation has a central vertex that stays fixed and everything else moves around that vertex in a circle.
